Caroline now wants to fight the law, which charities said could lead to 15,000 children being parted from a parent who has been deported.

What happened?

The couple got married

Caroline first met Carlos when she travelled to Ecuador in 2015. They fell in love and married in June of that year.

Caroline came back to Britain last year to give birth to baby Thomas, so he would have access to all the things she had when she was growing up – such as basic healthcare and education.

But their Right to Remain visa application was turned down by the Home Office, and Carlos faced having to leave his new child and Caroline. They were allowed to appeal, but it meant they could not travel while they waited for a court date.

It was only in July this year that the case was heard, with the judge quickly allowing their appeal.

But in the meantime they racked up a huge debt, living hand-to-mouth because only Caroline was allowed to work. They ended up living in a caravan at one point, because they could not afford a flat.

Asked for a comment on Carlos and Caroline's case, a Home Office spokesman said: "In February, the Supreme Court endorsed our approach in setting an income threshold for family migration that prevents burdens being placed on taxpayers and ensures migrant families can integrate into our communities. This is central to building an immigration system that works in the national interest.

"The changes in immigration rules announced in the written ministerial statement on July 20 do not affect this underlying policy but instead address the court's findings in respect of exceptional circumstances and of our existing statutory duty to consider a child's best interests.”
